Title: Mechanism for collating printed signatures
IPC: B65H39/055
Filed: 1945-05-11
Abstract: 598,255. Signature-gathering machines. CRABTREE & SONS, Ltd., R. W., and PHYTHIAN, T. E. May 11, 1945, No.11907. [Class 100 (i)] [Also in Group XXX] In a signature-gathering machine wherein receptacles carried by a conveyer are moved step-by-step transversely to a series of lines of signatures leaving a printing-machine, the pitch of the receptacles and the feed of the conveyer can be adjusted according to the size of the signatures. In one form Fig. 3, the containers 4 are mounted on wheels 5 the axles 12 of which are connected by adjustable links 7 to form an endless conveyer running on guides 6. To impart an intermittent movement to the conveyer, a reciprocating slider 8 carries a spring pawl 11 which engages the axles 12 in turn. If the size of the signatures is varied, the effective length of the links 7 and the stroke of the pawl 11 are altered to suit, the position of the pawl also being adjustable in a slot 21. If necessary the length of the guides 6 is altered, one end being slidable relatively to the remainder for this purpose. In a modification. Fig. 4, in which the conveyer is positively held during its periods of rest, a member 23 which engages an axle 12 to drive the conveyer and a similar member 24 which engages another axle to lock the conveyer operate alternately. The member 23 is adjustably mounted on a member 25 which is reciprocated horizontally by a link 13 adjustably connected at one end to a driving disc 15 and at the other end to the slide 8 and vertically by a cam 37 on the 'disc through a spring-controlled rod 35 connected by parallel links 29, 30 to a member 28 slotted to engage a pin 26 on the member 25. The member 24 is carried by a vertically-movable member 38 connected by a bell-crank.lever 41 to the rod 35. Both members 23, 24 are adjustable in slots 44, 45 in the members 25, 38 respectively. If it is desired to collect some of the signatures separately, guides 61, Fig. 8 (not shown), one of which is provided for each station, may be moved into position to deflect such signatures to pile tables 65 instead of to the conveyer. In order to ensure that the signatures lie flat in the boxes 4, each box is provided with fingers 44a, Fig. 7, which move inwardly so as to close a signature if it has partially opened, and downwardly, to press the signature, and then moves outwardly from the gathered batch. The fingers are mounted on blocks 45a fixed to a spindle 46 carried by a lever 47 oscillated from a cam 49 to move the fingers into or out of the box, the spindle 46 being oscillated from a cam 54 through links 52, 53 to impart a pivotal movement to the fingers.

A vaccine against the viral rhinopneumonitis infection of horses (viral abortion of mares) is manufactured by attenuating the rhinopneumonitis viruses, after initial cultivation, by a series of passages through primary cell cultures prepared from tissues that do not originate from equidae (Ungulata perissodactyla), until the viruses have lost those of their properties that are pathogenic for the horse, the viruscontaining harvests being, if desired, combined with an adjuvant e.g. aluminium hydroxide or aluminium phosphate, and/or, if desired, freeze-dried. Attenuation of the virus may be carried out by passages through cultures prepared from sheeps' kidneys (24 to 40 passages), piglets' kidneys (240 to 300 passages) or permanent cell-lines. The initial cultivation may be performed in a tissue culture obtained from an organ of a horse, cow, pig, sheep, goat, monkey or small animal such as the kidney of a horse or a piglet, from a permanent cell line e.g. BHK-21, AND HeLa, PK- 15, RK-13 Bulls; or a golden hamster.

Abstract: 786,726. Cooling dynamo-electric machines. GENERAL ELECTRIC CO. April 26, 1954 [April 24, 1953], No. 12016/54. Class 35. In an enclosed machine containing a cooling gas and with cooling liquid supplied to channels in the stator means are provided for detecting a leakage of gas into the liquid stream. As shown, the pressure of hydrogen is adjusted by the turbine governor and/ or a manual regulator 11a and is operative on the upper surface of adjustable diaphragm 18c in opposition to the liquid pressure for operating a valve 18a thereby regulating the liquid flow in proportion to the gas pressure. This liquid is drawn from a tank 15 by a pump 17 passed through a cooler 20 and is then passed through stator ducts of the generator and returns to tank 15 where it is splayed out from pipe 15b whereby any entrained gas will become separated and drawn off by vacuum pump 21 and be detected by a gas analyzer 24, or if the amount is greater, by flow meter 23. In the event of an extremely large leak, the pump 21 will become incapable of maintaining the preselected vacuum in the tank 15 and the bellows 25a will close the contacts 25c of a signal lamp 25e. The gas analyzer 24 could slao operate a signal or alarm. Specification 786,725 is referred to.

Filed: 1964-03-25
Abstract: <PICT:1003588/C6-C7/1> Selected proportions of different materials, particularly pigments, are electrophoretically deposited on to a substrate electrode, e.g. anodized aluminium alloy, from a colloidal suspension of such materials by adjusting the voltage applied between the substrate and a counter-electrode in the suspension to produce the desired composition, particularly of colour, of the deposit. Thus deposits of different colours may be produced from the same suspension or a constant colour may be automatically maintained from a suspension changing in composition, e.g. by depletion.  As shown, an anodized strip 40 from supply reel 38 passes around roller 50 in suspension 54 near to counterelectrode 48 to be coated with a dense electrophoretic deposit on one side, then passes over roller 52, through furnace 74 for sealing with steam, and then through washer 68 for washing off loose material to a sensing station 102 where light from source 82 is reflected from the strip and focused upon photosensitive device 90 which controls the potential supply 66 to the conductors 62, 64. For determining colour, a spectroreflectometer 80 may be used. Alternatively a device for measuring magnetic permeability or dielectric losses may be used.  The suspension may be maintained ultrasonically.  Examples of pigments used in suspension are flavanthrone yellow and phthalocyanine blue, and zinc and cadmium sulphides.

A winding and hands setting mechanism for a watch comprises a castle wheel 4 formed with ratchet teeth 5 and contrate teeth 6 and a stop 13 which a yoke 8 engages as the yoke is moved by a lever 14 in a direction to bring the castle wheel to the axial position in which the teeth 6 engage a hands setting contrate wheel 7. A crown wheel 2 formed with ratchet teeth 3 is freely rotatable on a stem 1 whilst the castle wheel 4 is movable axially but not angularly with respect to the stem. As shown, rotation of the stem causes the castle wheel to rotate the crown wheel 2 which winds up the mainspring. On pulling the stem outwardly, the end 17 of the lever is rotated by a notch 16 so that a tip 19 of the lever engages the yoke 8. The yoke is therefore rotated anti-clockwise against the pressure of a spring 12 and a stud 10 fixed to the yoke moves the castle wheel 4 into the hands setting position. When the yoke reaches the stop 13 the lever 14 bends the leg 21 of the yoke so that the tip 19 snaps into a notch 18 in the yoke.

Abstract: 886,730. Printing processes. RANK-XEROX Ltd. April 22, 1958 [April 24, 1957], No. 12732/58. Drawings to Specification. Class 100(2) A layer or pattern of finely divided particles such as powder particles are transferred from an insulating surface associated with a conductive backing to a conductive receiving surface by applying an electrostatic charge in such a manner that the particles are released from the insulating surface and attracted in image configuration to the receiving surface when the latter is successively placed into and out of contact with the insulating surface. A uniform charge is applied to the particles and the insulating surface, and the transfer takes place while an electrical connection is established between the receiving surface and the backing. In order to obtain a better image, an insulating sheet is placed over the image, an overall charge having the polarity of the powder forming the desired image is applied to the sheet, and the sheet is removed, carrying with it any particles of opposite polarity adhering to the non-design areas of the surface. The transfer process then takes place as before. In one form, an aluminium plate member is partly covered with a vacuum deposited vitreous selenium photoconductive layer and is contained in a holder where it is covered with a dark slide. A metal lithographic master is placed on the slide, and the slide withdrawn so that the master lies on the selenium coating and contacts the aluminium plate where it is not coated, to make the necessary electrical connection. The master is then lifted off with the adhering powder image.
